"the prompt FAKEPAUSE provides, playback will resume where it left off. "
"The usefulness of this command is that it forces XMMS to release the "
"output device until you unpause it. Technically it does this by saving "

"Then, when it unpauses, it jumps back to the saved position in the song "
"and resumes playback."
